This pattern was used at the bottom of a quilt to look like the centers of the larger triangles at the top. I called the quilt "Triangle Confetti." You can see the quilt here: http://createinthesticks.blogspot.com/2014/03/triangle-confetti.html
I had a lot of requests for the dancing triangles at the bottom, so here is the pattern you requested.
I've shown a few other ways you could use this pattern for a quilt.
